Enjoy your slow charging tripping hazard then. Magsafe saved my 14 inch Pro when my roomba ran over it.
There's no reason Apple could not have made a breakaway USB-C cable, and had it be a higher charging speed as well. I used a breakaway USB-C cable with no issues when traveling with my MBP.
Apple would have made a MagSafe for the iPhone too had not EU got in the way stifling all innovation.
There's nothing in the spec that prevents Apple from designing a MagSafe USB-C cable. The EU directive merely requires a USB-C port and some minimal charging specs; it does not specify how the rest of the spec is implemented nor prevent custom cable designs beyond the USB-C port.
There's plenty of room to innovate; a company could have a special USB-C high speed power/data cable while a standard USB-C cable would charge at the base PD level. Apple could even implement a version of MiFi for such a cable; and still meet the USB-C spec and EU law.
